That makes sense given the structure of the society, no? If you were to build an organization whose purpose was a predictable amount paid out to the senior most members committed ahead of time for an indefinite period, you would prioritize predictable income. In the ideal, your contracts would all be long-term contracts that don’t fluctuate very much.

Any entity that seeks to take risks to earn outsize income increases the income variance and makes it hard to organize your committed payouts. So you are forced (by your priorities) to discourage the entrepreneur and freelancer and encourage the 18-60 salaried employee. Fixed fungible production unit can be used as an input to a machine that produces committed output.

Then you import guest-workers etc. to improve throughput. You are forced by your priorities. Probably the expansion of the US welfare state will meet similar constraints soon enough.

It’s a bit just-so so I think there’s an over-claim in there but I think the seed is there.
